'ro ALL WHoM IT MAY eoN'eEnN; e

Be it known that I, IIORCE S. HOXIE, ofAdrian, county of Lenawee, andState of Michigan, have invented anew and useful ImprovementinPlough-Coulters; and I do hereby declare the following to be a full,clear, and exact description, which will enable others skilled in theart to make and use my invention, reference being had tothe accompanyingdrawings, and to thelettcrs of reference marked lthereon, making ,a partof this specification.

Iiikeletters refer to like parts. The nature of my invention consists inproviding the coulters oi' agricultural ploughs with either a permanentor an adjustable mould-board, in such a manner that when the plough'isdrawn along, the mould-board on the coulter' turns up a thin and narrowfurrow, which is afterwards turned under by the plough, thus completelyburying all the stubble, turf, and other surface-matter.' In thedrawings- Y i i Figure 1 represents a plough-coulter, having an adjustablemould-board attached, and embodies my invention,

Figure 2 represents a back view ofsuch a coulter and mould-board, whenviewed in the direction of xy, iig. 1.V

Figure 3 represents a sectional view of the brace D, and the mode ofattaching it tothe coulter.

Figures 4 and 5 represent side views of modified vforms of the other twobraces, a and b. shown in fig. 2.- A represents the coulter.' i i Arepresents the plough-beam.

B represents the mould-board.

`D represents the lower brace. i

a and b, in figs. 4 and .5, are but modified forms ot' the braces,represented by like-letters in g. 2.

'lhe mould-board B is constructed of steel, bent or curved in the properformand secured to the braces a, b, andD by short bolts, and the bracesav and b are bolted to the coulterA bythe boltsc c, fig. v2; or thecoul'-l ter A is tapped, and the braces Vaand b, formed as shown in igs.4 and 5, are screwed directly into it. a

The lower end of the brace D is to be secured to the coulter A means ofa hooked tenen, h, fitting into a corresponding slot in the coulter, aplug being driven into the slot forward of the tenen, to prevent it`from sliding-ahead. But in regard to the use of this brace D, I do notwish to be confined lto the employment-of 'a hooked tenon to secure itto the coulter; but' my design is (if it is desirable) .to tap thecoulter A, and screw -this brace D also into the coulter, in the sameway that the braces a and b (figs. 4 and 5) are screwed vto the coulter.

I havedesigned also (ifvdesirable) not to use the braces a, b, or D atall, but to4 construct the coulterAand mould-board'B bothin one piece,by welding them together,'retaining, however, the same form for themould-- board B.

The mould-board B is placed at any desirable height above thepoint ofthe coulter, so aste turn upathn and narrow furrow of the surface-earth,and throw it over on 'the ground, to be thrown under by the plough. thewhole to be attached to (and if desirable, be detachable from,) anycoulter of the common form.

Having thus described my invention, 'what I claim as-ne\v, and desire`to secure by Letters Patent, is

Gleim.

1. I elaim,in combination with the coulter A, the braces a, b, and D,mould-board B, tenon L, all constructed in the manner set forth anddescribed.

2. I claim the combination of the mould-board B and coulter A', whenboth are made in one piece, orwelded together in the manner set forthand described. y
